pyx-user — PyX user

[PyX-user] Multi Page documents

[Maarten v. d. V. <m.h...@gm...>]

Dear all,

I wonder if you can help me.

I would like to create multi page documents in Pyx. I am browsing through the documentation and the mailing list archive, but I am not able to connect all the pieces of information. 

I have tried following along:

https://sourceforge.net/p/pyx/mailman/message/6193313/ <https://sourceforge.net/p/pyx/mailman/message/6193313/>

c = canvas.canvas()
c.text(0, 0, "Hello, world!")
c.stroke(path.line(0, 0, 2, 0))

page = document.page(c, paperformat=paperformat.Letter)

result = canvas.document(c)
result.writePSfile("Whatever")
But this gives me the error:

AttributeError: 'Document' object has no attribute ‘page'

Did the package change since this thread? (2007…) Is there a working example somewhere that I could use instead?

Thanks,

Maarten

HI  André,


Thanks for the fixes,  they worked like a charm.

Re: [PyX-user] Struggling with text on canvas.

[André W. <co...@wo...>]

Hi Frederico,

the methods with _pt at the end, use coordinates in postscript points, 
whereas without _pt PyX uses PyX lengths. Those can be configured by the 
unit module. PyX lengths default to cm, but you might reconfigure it to 
mm to match your expectation.

Please find this correction (to mm) together with a few other small 
fixes below. To my mind it now basically runs as you probably expect it.

Best,


André

[PyX-user] Struggling with text on canvas.

[Frederico C W. <fr...@gm...>]

Howdy,


I'm trying PyX for the first time, and looking to adapt examples to my
need,

but after some effort, couldn't get the text to appear on the canvas.


Thought it would write the text somewhere near the drawn vectors. .. but
it hasn't  text anywhere.


Would appreciate some help here.


Thanks in advance.,

Re: [PyX-user] Fwd: How to reduce the file size ?

[Vignesh T G <vig...@gm...>]

Hello André,

Yes you are right, the compression is switched on by default. By mistake, i
checked the size of a different file.
I have to reduce the size of the input data to the plot.

PS: Sorry for the repeated replies.

Regards
Vignesh

Re: [PyX-user] Fwd: How to reduce the file size ?

[André W. <co...@wo...>]

Hi Vignesh,

perfect answer by Michael already (thanks!). Just an additional remark: 
The default is to compress the page content stream and j.writePDFfile 
('plot', write_compress=False) will disable the compression. So it will 
become even bigger, but allows you to view the content in an editor. 
Now, how to reduce the size? The only option is to try to reduce the 
amount of data to be included ...

Best,


André

Re: [PyX-user] Fwd: How to reduce the file size ?

[Vignesh T G <vig...@gm...>]

Hello Michael and André,

Thank you for the replies and sorry for not providing an example.  I was
able to reduce the file size using Michael's suggestion, and the script is
given below


j = graph.graphxy(width=8, height=8,
                  x=graph.axis.lin(title=r"$\Delta y/R_o$ "),
                  y=graph.axis.lin(title=r"$\Delta{V}/Uc$"),
                  )

j.plot([graph.data.values(x=x, y=v,
                          title=r"$\Delta y/R$")],
       [graph.style.line([style.linestyle.dashed, style.linewidth.thin,
color.rgb.black])]
       )
j.writePDFfile('Eq_Behavior',write_compress=True)

Regards
Vignesh

[Michael J G. <mic...@us...>]

Hi Vignesh

You didn't provide a complete example, but I assume that your "j" is a
canvas.canvas instance, right?
The writePDFfile method of canvas creates a document.page and calls
document.document's writePFfile method for you. If you want to specify
keyword arguments for the latter when you use canvas.writePDFfile,
write them as "write_compress" etc.

[PyX-user] Fwd: How to reduce the file size ?

[Vignesh T G <vig...@gm...>]

Hello Pyx Development Team and users,

I am generating a simple line plot using pyx in 'pdf' file format.
Unfortunately, due to the data i have, the resulting file size is large. I
found in the manual, about the 'compress' function in the module document
but i don't know how to use it. Can someone help me in this regard?

I tried  "j.writePDFfile ('plot', compress=True, compresslevel=6)", but i
get an error message stating there is "an unexpected argument compress and
compresslevel"

Thanks

[PyX-user] front-end for pyx

[Serge D. <ser...@ij...>]

Hello,

  This is not a request for help in using PyX, so I hope it still has 
its place on this list.
I made 'seplot' a small interface for PyX, to be able to use it from 
bash, or from python, with a simpler syntax than the whole thing. 
Typically, in bash :

$ seplot data.txt

Would yield a PyX-generated plot of data contained in data.txt. There 
are quite a few possibilities to meet real-world needs (if conditions, 
axis range, histograms...).

Seplot can be installed through pip ( $ pip3 install seplot ) and 
downloaded from github :

https://github.com/SergeDmi/Python-Tools/tree/master/seplot

Hope this has some interest,

Serge

I had noticed this as well. It seems that setuptools should be used
instead of distutils. I will prepare a PR and see what Jörg and André
make out of it. For the moment, you can simply try to replace
distutils.core by setuptools in the import.

It now installs without the warnings I mentioned.  Thanks.

I experience two other warnings installing from source (Python 3.8.0b3 on Win 10).

C:\Program Files\Python38\lib\distutils\dist.py:274: UserWarning: Unknown distribution option: 'python_requires'
   warnings.warn(msg)
C:\Program Files\Python38\lib\distutils\dist.py:274: UserWarning: Unknown distribution option: 'extras_require'
   warnings.warn(msg)

To be clear: I am reporting these warnings fyi, but they do not seem to be affecting
any aspect of the installation.

Thanks for your quick fix,
Alan

Re: [PyX-user] [PyX-devel] ANN: PyX 0.15 released

[Michael J G. <mic...@us...>]

Hi there,

Py3.8k is more picky about escapes, some warnings will even turn into
errors. In particular, this is about "unnecssary" escapes, i.e. escaped
characters which need not be escaped. From a quick first glance at the
reported files they fall into two categories:

- LaTeX code such as \overline in a docstring which is not marked as
  raw string
- commands such as \s in regex expressions which are not raw strings

Cheers
Michael

I was unable to reproduce your problem with Python 3.8.0b3. There was no
problem installing PyX 0.15 and it worked fine on a few examples. Can

Re: [PyX-user] Adjacent lines...

[Michael J G. <mic...@us...>]

So, I finally figured out how to add stuff to the gallery. Can't say
that I'm overly thrilled. For example, I see no way to control the
bounding box (no, struts don't count) or scale of the nbviewer output.
My local nbviewer as well as the hosted one give me svg for the cell
output so that I have to create the png preview for the gallery
manually. Oh well. Doing this directly on github (binder/nbviewer)
would be much easier. I guess my next project will be a mirror for the
examples and the gallery...

In any case, "parallel" can be considered to be an example which you
should grasp before wrapping your head around the "knot" example. I
guess the gallery is really meant as a showcase of things which PyX
can do; in the current state of PyX "development", it's maybe our only
way of adding examples.

BTW: If you run "parallel" yourself and try to enlarge the bounding
box you get the funny effect that bboxenlarge=0 and bboxenlarge=0.2
lead to the same clipping on the left (while the bbox is enlarged
vertically), only larger bboxenlarge values enlarge the box on the
left. I haven't found the root cause yet.

Re: [PyX-user] Adjacent lines...

[Michael J G. <mic...@us...>]

http://pyx.sourceforge.net/examples/drawing2/parallel.html

should give you a good example. You can tweak the construction of the
parallel further (as indicated in the text), by specifying what to do
with corners.
Also, remember that you can decorate a path without stroking it
("draw" without stroke/fill), and that you deform a path and then work
with the deformed path
(http://pyx.sourceforge.net/manual/deformer.html#deformer.deformer.deform):
In the example, the deformed path (which is stroked in blue) would be

deformer.parallel(0.2).deform(p)

which you use to build upon.

Rather, it seem it should be possible with the deformer module perhaps?
What would such code look like?

[S J. S. <swa...@gm...>]

Is there any easy way to make a curved path line that is
adjacent/non-overlapping metapost to another curved path? It seems this
should be possible with the deco somehow. Thank you.

Thanks. This is really helpful. I do recommend it be added to the
documentation. Please do.

Hi Gert,

I need to fix a few bugs first :)

I knew that deco.colorgradient reverses the path - I just don't know
why. The code seems rather inefficient, splitting the path N times for
steps=N rather than doing one split for the list of parameters. I
don't know why, either. I even suspected that it misses one color
patch at the end, but it appears gradients take care of that (mapping
N-1 to the end color). Nothing to fix here.

Investigating that I noticed that one should draw the path, not stroke
it, since the decoration strokes already. Otherwise you may notice a
small hairline around the gradient (decoration) stroke stemming from
the stroke being decorated.

Also, gradient filling a closed path sems to be such a common thing -
there should be a decorator for that, taking a gradient and a path or
direction vector, with the decorator figuring out the scaling (and
linewidth) for the gradient path and stroking it to a canvas clipped
by the path being gradient fill decorated :)

Cheers
Michael

It might be a good idea to add this example to the PyX gallery.

Best regards,
